4 claims. (c1. 285-10) lY V This invention .relates to improvements insteam joint attachments for rotary steam heated cylinders used in thepaper making and other industries.

One object of the present invention is the provision of a steam jointattachment including interchangeable vparts designed for selectiveassembly to provide either a syphon-type or a bucket-type steam jointattachment.

Another object is to provide a convertible steam joint attachment of thecharacter described which is simple in design; is composedvof relatively few parts; and can be manufactured and sold at a cost comparingfavorably with the cost of the syphon-type and bucket-type steam jointattachments now available.

A further object is the, provision of a syphontype steam jointattachment in which the steam delivery pipe and the syphon pipe aresupported in a novel manner so that no supports for these elements arerequiredV within the cylinder itself.

A still further object is the Three Rivers, Quebec, Canada Serial No.753,275

It comprises a tubular member 1 open at both f ends and provided with anend flange 8 which of journal so est journal is fastened by bolts 9 andnuts 9a to thevend that member 1 rotates with said Member 1 extendsthrough a stationhousing I0 provided, at the end near- 5, with aremovable end wall sejournal. ary bearing cured in place by bolts I2 andhaving a central opening for the passagev of member 1.

provision of a syy phon-type steamjoint attachment designed so that allthe component parts except the syphon pipe can be readily detached fromthe steam heated cylinder without removing the syphon ipe.

Other objects, advantages and characteristic i features of the inventionwill be more readily understood from `the following detailed descriptiontaken in connection with drawings, in which- Fig. 1 is a.longitudinal'sectional view of my attachment as it appears when1improved joint the component parts areass'embled to provide asyphon-type attachment.

Fig. 2 is a right hand end view of the attachment shown in Fig. 1. Y

Figs. 3 and 4 are detail views illustrating the manner in which thesyphon pipe shown in the preceding figures is supported by and clampedagainst the delivery end of the steam delivery pipe. Y

Figs. 5 and 6 are views similar to Figs. 3 and 4 but showing a slightmodification.

Fig. 7 is a fragmentary sectional view of the joint assembly as itappears when the'syphontype casting shown in Fig. 1 is replaced by abucket-type casting; and

Fig. 8 is a right hand end view of shown inFig. '1. Y

In Fig. 1 the steam heated cylinder to which my improved syphon-typesteam joint assembly the assembly the accompanying A sealing-ringretaining plate I4 is .fastened tothe outer surface of end wall II byscrews I5 Iand is 'provided with an inwardly facingrecess I6 in which asealing ring I1 is arranged so that said ring is clamped between wall Iand an opposing wall of saidrecess. The inner' edge of ring bearsagainst member 1 and serves, in conjunction with the labyrinth sealinggroove I8 in the defining wall of opening I3, to seal said opening,

At its opposite end-housing ID yis provided with an integral end wall 20provided with an inwardly facing recess 2| and an outwardly facingrecess 22. A sealing ring retaining plate 23 is secured in recess 22 byscrews 24 and serves tohold in place a sealing ring 25 which bearsagainst the tubular member 1 which passes through a central opening ofwall 20.

Member 1 is journalled in bearing housing ID by two anti-frictionbearings 21 and 28. These bearings are separated from each other by aninterposed spacer sleeve 29 encircling member 1. Bearing 21 is arrangedimmediately adjacent the removable end wall II of housing I0 and bearsagainst a shoulder 30 of member 1. Bearing 28 is arranged adjacent endWall 2|) of housing I0 and is engaged by clamping nut 3| which 1sthreaded on member 1 and is accommodated in recess 2|. The completebearing assembly, including bearings 21 and 28 and spacer sleeve 29, isclamped in place between the shoulder 3|] of member 1 and clamping nut3|. The space between bearings 21 and 28 constitutes a lubricantreservoir 33 and is provided with a lling plug l34 and drain plug 34a.

Bearing housing I0 is provided with upper and lower arms 36 projectingbeyond the end wall 20. These arms36 are detachablysecured, by bolts 31and nuts 38, to the flange 39 of a hollow stationary. casting 4l).
